Unlike most gaming mice, the CM Storm Reaper has an aluminium element to its construction, meaning it matches the Mech and Pulse-R aesthetically. The main body of the mouse is constructed from black plastic, though. This plastic is finished in soft-touch paint which offers more grip than standard paint. The aluminium plate can actually be removed, meaning it would be fairly easy to customise the mouse.
The build quality of the Reaper cannot really be faulted. The aluminium plate integrated into the palm area of the mouse gives the unit a reassuring level of rigidity and all of the plastics used in construction feel very good quality.
CM Storm have chosen to use a right-handed ergonomic form factor for this model which is perfectly shaped for right-handed use. We would recommend that left-handed users opt for a different model, though.
The left and right buttons feature high quality Omron switches which have a very refined action. They are perfectly weighted so that they can easily be depressed in quick succession and aren't easily activated accidentally.
We are a little less impressed with the mouse-wheel. We love the look and design of the wheel as it appears to have been milled from a single piece of aluminium. However, the surface is too slippery to control accurately and it takes too much effort to depress it. There are a pair of DPI switches located just behind the mouse wheel which can be assigned to different functions if desired.
Moving round to the left hand side of the mouse, there is a sculpted thumb alcove which features browser forward and back buttons, as well as a programmable ‘clutch' button, which can be configured using the downloadable software utility.
CM Storm have chosen to restrict the LED lighting to white only, which ensures that the Reaper has a sophisticated appearance.
